Abstract
EEG was recorded at Fz, Cz and Pz while 35 participants either listened passively to tones or completed an oddball task. Significant positive and negative correlations were found between the ERP string length measure and WAIS-R Performance IQ and Verbal IQ. The most important factors influencing the sign and magnitude of string length by IQ correlations were the experimental task and the region of the ERP trace used for calculating string length. Other contributing factors were the electrode site and whether or not the ERP trace was scaled before calculating string length. The formula used to calculate string length had little effect. Significant negative correlations were found between the ERP variance measure and WAIS-R Verbal IQ and Full Scale IQ. © 1999 Elsevier Science Ltd. All rights reserved.
